60s researcher

Lu Jian frowned, still a little surprised in his heart, he thought that the kid should have good grades when he saw that kid before, but he didn't expect to see him at Tsinghua University, and he was actually a student of the computer department of Tsinghua University, majoring in software engineering , Becoming my student, this is quite a fate, but this kid looks a lot darker, and a lot stronger, even his temperament is a little different from before, he looks a lot more stable and reliable.

Thinking this way in his heart, Lu Jian didn't mean to reject him, and was going to go over to say hello to him. After all, we got along quite happily before, and then it was a teacher-student relationship.

Liu Luhua and a few people from his class came a bit late, the front was already full of other people, so there was no other way but to go to the back.

Seeing Lu Jian coming, Liu Luhua was very happy, and quickly changed seats with his classmates, and sat on the edge of the row, "Comrade Lu Jian, are you also here to take the [C language] course? Is it also our software engineering major? Why haven't I seen you before?"

Liu Luhua's uncle is an officer in the army. He couldn't see his lazy appearance. After Liu Luhua's college entrance examination was over, he was arrested in the army below and directly let him participate in the army's daily training for recruits. He didn't even let him go during the Chinese New Year. , I have to stand on guard frequently, which is very hard. I didn't release him until the beginning of the school report.When he came back, the news that Lu Jian was the No. [-] student in the college entrance examination had long been replaced by other news, and the banners at the gates of the family courtyard and the research institute had long been taken down.

Liu Luhua only knew that he was admitted to Tsinghua University, but he didn't know that Lu Jian was the top student in the college entrance examination this time.It was only after he entered the university that he realized that he was watching the sky from the bottom of a well. He was constantly absorbing new knowledge every day. He had already forgotten about Lu Jian. I don't know each other anymore.

Lu Jian smiled, and didn't answer his question, just said: "You are a software engineering major? How are you studying recently?"

Liu Luhua didn't care about Lu Jian's evasion, he thought in his heart that he hadn't been admitted to Tsinghua University, and now he was looking for an opportunity to listen, so he put down the previous question and replied, "Yes, I am from the third class of software engineering. Students, you have been studying well recently."

After finishing speaking, without waiting for Lu Jian to speak, he continued: "Oh, you don't even know, I was unlucky during the winter vacation. My uncle said that I was directly drawn into the army, and I have been training in it, which can be regarded as a blessing for me. I was so exhausted, even my father and the others helped me get the admission letter."

As he spoke, he sighed, obviously expressing a deep and indescribable expression about the previous experience.

Several young people who were with Liu Luhua looked at Lu Jian very curiously, and were about to ask Liu Luhua who this was, when they heard the bell ringing outside the classroom.

For a moment, everyone stopped what they were doing, looked at the podium and the door very seriously, and waited for the teacher to come in for class.

"Comrade Lu Jian, hurry up and find a place to sit down, we are about to start class." Hearing the bell ring, Liu Luhua was a little anxious, and hurriedly asked his classmates to make room for Lu Jian to sit down.

Lu Jian smiled at him, didn't speak, and then walked down.

"Comrade Lu Jian..." Liu Luhua was really anxious now, and was about to pull Lu Jian back, when he saw Lu Jian take a few big strides, and stood on the podium in the classroom, and slipped out of his suit He took out a pair of glasses from his pocket, and immediately his whole person became a little different, looking refined and imposing.

Liu Luhua was still at a loss, not knowing what Lu Jian was going to do, so he could only sit there blankly, staring at Lu Jian above with his glasses.

When Lu Jian walked towards the podium, he had already attracted everyone's attention. When Lu Jian was standing on the podium and no one else came in at the door of the classroom, many of them would have guessed it. The one on the podium should be their [C language] teacher.

Seeing almost a hundred people's eyes focused on him, Lu Jian didn't panic at all, coughed lightly, and said to everyone: "Students, hello everyone! I am the teacher of the [C Language] course. Teacher, Professor Lu Jian of Tsinghua University, you will study with me for a long time. Our course has 68 class hours, two class hours per week, and it is expected that the course will end in the next semester, and there will be an assessment at the end of the semester."

After finishing speaking, Lu Jian ignored the surprise in the eyes of the people below, and continued: "Okay, this is probably the case. The monitors of each class will count the number of people, and if anyone skips class, please let me know. There are 3 minutes now, please." you guys."

"Okay." Three people in the classroom immediately stood up and counted the number of people in their class. The speed was very fast, and they were all counted in less than 3 minutes. Everyone arrived, and there was no sign of skipping class.

Lu Jian nodded and asked them to sit down, and then said to the people below: "Okay, since everyone is here, let's start the class, but before each class in the future, the monitors of each class will count themselves. If you have any questions about the number of people in the class, you must tell them in time."

"Understood." Nowadays, people still have a sense of responsibility, and the three monitors agreed without hesitation.

After that, Lu Jian began to give lectures, "C language is a computer language, it has the characteristics of high-level language and assembly language, and it is mainly used to write system software..."

Lu Jian spoke in a leisurely manner. These people have no foundation at all, and some people have never even seen a computer, so he explained it in more detail. Not only did he explain the development history of this computer program system, but also It also explained the history of computer development. Even if you are engaged in software and system development, you still need to have some understanding of computer hardware.

He spoke seriously, all of which were pure knowledge and dry stuff, and he didn't use too many skills in the lectures, but he spoke very fluently, and the people below listened very carefully, although some people frowned from time to time because they were a little hard to understand Brows frowning, but most of the people were copying the notes very seriously, and everyone was flying with their pens. Even Liu Luhua, who was still in a daze just now, was fascinated by what he heard.

The time of the two classes passed quickly, and when the bell rang for the end of get out of class, the blackboard behind Lu Jian was already filled with densely packed things, all of which were written by Lu Jian just now.

Lu Jian didn't delay their time, there were other classes after that, although today's progress was a bit slow, these people had never had much contact with computers before, so there were many difficulties, Lu Jian didn't want to delay the next teacher's class, directly Put the chalk in your hand back into the chalk box on the podium, and then said to the people below: "Okay, this is the end of today's lesson, if you have any questions that you don't understand, you can write it down first, and I will wait for it tomorrow." At 08:30 in the morning, you will be in the office of the department, you can tell your questions to the monitor, and then go to the office to hand it over to me after the monitors of each class have summed up, and I will answer these questions for you next week."

"Of course, if you have time, you'd better read more of the C language textbooks in your hands."

"Understood." The students present quickly nodded in agreement.

After speaking, he took off the glasses on the bridge of his nose, wrapped them in a square scarf, and put them in his pocket.

Seeing that these people agreed, Lu Jian left without any intention of staying any longer.

After Lu Jian left, the boys who had a good time with Liu Luhua immediately surrounded Liu Luhua.

One of the thin and tall men seemed to have the best relationship with him, and put his hands around Liu Luhua's neck, "Comrade Liu Luhua, tell me the truth, how did this Professor Lu meet you? Are you related?"

They are about the same age, they are the oldest in their dormitory, so they have the best relationship, and they don't speak so politely.

Liu Luhua gave him a blank look helplessly, "We just know each other, we're really not my relatives, but..." He was also at a loss about the current situation, completely unaware how Comrade Lu Jian, who just took the college entrance examination, could become a member of their department It's really hard to imagine a professor, or a full professor.

"But what?" Several other people were anxious, but they were very curious.

Anyway, this is not a secret, Liu Luhua thought for a while, and then continued: "But when I took the college entrance examination, he sat in front of me. He also took the college entrance examination this year. He was just a high school student before."

"What? Our [C language] professor is actually a high school student?" Everyone sitting near him was surprised.

"Professor Lu is not an ordinary high school student. He is also a senior researcher at the Capital Computer Research Institute. The air conditioners and washing machines we use now are all developed by him, as well as the CNC machine tools and the machine tools we are using now. Not only that, the C language we are learning now was developed by this professor Lu, but also personal computers, and computer supporting equipment such as printers, photocopiers and scanners, can be our professors. It is hard to imagine that he used to He's actually just a high school student, and he's still an expert in mechanical research."

The people present almost dropped their jaws when they heard his words, their eyes protruded, and they couldn't believe it. No one spoke for a long time.

He asked his grandfather about these after the college entrance examination, and he was similar to them at the time, so he was a little afraid to meet Lu at the time. He planned to do some psychological preparation first, and then go to see Lu later, but he didn't expect His uncle threw himself directly into the barracks.
